When mail is sent from my domain to external email addresses, it uses the internal (non-routable) domain name , e.g. mailserver.nonexistentdomain.loc, which obviously causes mail to be rejected if it is checked for reverse dns lookup. If I use the external fqdn of mailserver.valid_domain.com in the fqdn box (smtp virtual server properties - delivery options - advanced) , will that solve the problem & / or will it cause confusion for my DNS records. In short, does this setting simply change the fqdn of outbound smtp messages or does it impact internal DNS name resolution ? thanks, -- Steve Paul
It doesn't trouble internal and does exactly what you want.
